Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of recording, displaying and transferring video information.

[0002]

2. Description of the Related Art Conventionally, a magnetic tape has been used as a recording medium for recording video image data. Magnetic tapes are suitable for such video recording applications as inexpensive, high density, and reusable media.

In general, it is usual to record video data on a magnetic tape in the order in which they were taken. Therefore,
When editing a shooting result or searching for a scene to be referred to, rewinding and fast-forwarding work for searching for a desired scene frequently occurs. In fact, on TV stations,
It seems that how well this work can be done is an indicator of the degree to which the worker has completed the cram school.

The following two points can be cited as the causes of such complicated work.

(1) Since the video recording medium is a magnetic tape,
In the first place, only sequential access is possible.

(2) Video data is continuously recorded and is not divided for each scene at the time of shooting. Therefore, in order to edit the image, it is necessary to look for a scene transition while looking at the video tape that has been shot on the monitor screen, and to determine the edit points of cut-in and cut-out.

The following measures can be considered for the above problems.

First, with respect to (1), the video recording medium is changed from a magnetic tape to a disc-shaped recording medium such as a magnetic disk or an optical disk. As a result, it becomes possible to randomly access the video data, and the conventional work of rewinding the magnetic tape and fast-forwarding becomes unnecessary, and the necessary video data can be directly taken out.

Regarding (2), for example, the head (Japanese Patent Application No. 2)
-230930), it is possible to divide the captured continuous video data into video data for each individual scene by using computer technology. In addition, JP-A-5-
In 198141, "Video Editing System", a technique is described in which a scene number is recorded on a magnetic tape with one scene from a recording start including a pause release to a recording stop including a pause during shooting.

However, the prior art relating to the above-mentioned scene division (2) has the following problems.

First, in the method of dividing photographed video data using computer technology, it is not possible to divide the photographed video data into scenes at the time of photographing 100% accurately because the photographed video data is processed later. The problem is that it is possible. This problem remains even if the accuracy of the algorithm is improved.

Next, regarding the method described in Japanese Patent Laid-Open No. 5-198141, since the scenes are divided at the time of shooting, there is no discussion related to the above-mentioned processing after shooting. According to this method, it is possible to accurately grasp the cut-in and cut-out edit points at the time of shooting after shooting. However, the recording medium of this method is premised on the magnetic tape, and the problem of the above (1) still remains. Further, since the information given to each scene at the time of shooting is only the scene number, all scene designations such as editing must be performed by the scene number. The work is complicated, such as having to write down the necessary scene numbers in advance. The scene number is recorded on the control track corresponding to the video signal of each scene. Therefore, since the scene number cannot be confirmed until each scene appears on the tape, the work becomes sequential.

On the other hand, when editing or retrieving video image data, various incidental information at the time of shooting, such as information such as shooting date and time and place, is often required. With such incidental information, it is possible to understand what the scene was shot and in what situation it was shot. In the conventional case, such information is separately created and saved as a memo. However, if such information is electronically stored together with the video data of each scene, the management of this information can be facilitated. Also, it becomes possible to use this for scene search.

On the other hand, some home-use video cameras and the like have a function of recording date information by superimposing it on the screen. This is convenient because you can see when the video was recorded by looking at the screen, but it is always displayed and cannot be erased. This is when you want to retrieve only the video information. In addition, since it is recorded as an analog signal, it cannot be used as a search key when searching.

[0015]

SUMMARY OF THE INVENTION In view of the above situation, the present invention records related information at the same time as captured video data at the time of shooting, so that the subsequent video data can be edited or searched for. The purpose is to make necessary information available.

[0016]

In order to achieve the above object, the present invention uses the following method.

In the video camera device, an index area is provided in a specific portion of the video recording medium, video data is recorded in the video recording medium upon the depression of the shutter switch, and the index area is actually recorded in the video recording medium. The address of the position where the video data is recorded, the video data length, and the related information of the video data are recorded.

Various types of related information can be considered. One of them is one or more representative screens in the video data. Further, as a typical example of the representative screen, there is a top screen of the video data. As another example, the shooting date and time when shooting video data, aperture value, focal length, screen movement information such as zoom and pan, location information of shooting location, shooting direction, temperature, atmospheric pressure, humidity, etc. There is information that can be obtained, and information that can be input from an additional input device such as a shooting place name, weather, and notes.

A plurality of representative screens or related information recorded in the index area of the video recording medium are displayed as a list on a display screen built in the video recording / reproducing device or a display device connected to the outside of the video recording / reproducing device. Further, by designating one representative screen in the list display by a position input device or the like, the video data represented by the representative screen is projected on the screen of the display device. Also, a plurality of representative screens or related information recorded in the index area of the video recording medium are output in a list display format to a printer device connected to the outside of the video recording / reproducing device.

The video recording medium may be a conventional magnetic tape device, but may be a disk device or a fixed memory device.

Further, in the structure in which the video recording / reproducing device is connected to one end of the communication line and the video display device or the video recording device is connected to the other end, in the first step, the video recording / reproducing device at one end is connected. Transfer the list data of the representative screen information recorded in the index area of the video recording medium,
The list data is displayed as a list on the video display device at the other end, and in the second step, from the displayed representative screen,
One or more representative screens are designated by the position input device, etc., and in the third step, only the video data related to the designated representative screen is transferred from the video recording / reproducing device to the other end of the communication line. Transfer to.

In the above description, together with the representative screen list data transferred in the first step, shooting date / time, aperture value, focal length, screen movement information such as zoom and pan, position information of shooting location, shooting direction, temperature, At the same time, electronically obtained information such as atmospheric pressure and humidity, and one or a plurality of pieces of information that can be input from an additional input device such as a shooting place name, weather, memorandum, etc. are simultaneously transferred.

[0023]

As described above, when the shutter switch is pressed, the recording address and the video data length of the video data are recorded in a predetermined index area, so that the video data of one continuous scene at the time of shooting is recorded as individual data. It becomes possible to record in a form that can be handled separately. By using the recording address and the video data length of the video data recorded in the index area, the video data of a desired scene can be directly read. Also, it becomes possible to record related information such as a representative screen together with the video data of each scene, and the related information can be stored in the index (required later in the scene such as editing or searching of the video data). It can be used as a search key).
The representative screen recorded as the related information may be the top screen as described above, but may be a screen other than the top screen.

The acquired related information such as the representative screen is displayed as a list on the screen of the display device. by this,
What kind of scene video data is recorded on the video recording medium can be seen at a glance. Furthermore, by selecting one of them with a position input device such as a mouse, the designated screen can be projected on the screen and the contents can be confirmed. By outputting this list display to a hard copy device such as a printer, it becomes possible to manage a content list of video data on a paper medium that is easy to refer to. Further, since more items can be output on the paper medium than on the normal disc play screen, it becomes easy to check the list of the video data recorded on the video recording medium.

Further, by using a disk device or a fixed memory device as the video recording medium, random access can be made as compared with the magnetic tape device, and quicker and easier editing / searching work can be performed.

When the recorded video data and related information are transferred to another place, as described above, first, the representative screen information and associated information such as shooting date and time are sent, and only the necessary representative screen is selected from the information. By specifying, it becomes possible to send only the necessary video data. As a result, it is not necessary to send all the video data, and the transfer time of the video data can be saved.

Specifically, it has information corresponding to the track address of the disk device and the sector address in each track. Further, when the disk device is composed of a plurality of disks, it also has information indicating which disk it is.

422 is the video data length. Specifically, how many frames (or how many fields) each video data is
It has data about whether it consists of unit images of.

Reference numeral 423 is information regarding the representative screen. Although FIG. 2 shows an image diagram in which the leading end screen of each video data is used as a representative screen, it is not necessarily limited to the leading screen. A screen in the middle or at the end of the video data may be held as a representative screen by an appropriate algorithm or user designation. Further, although FIG. 2 shows an example in which the address storing the actual screen is used as the pointer as the representative screen information, the corresponding screen information may be stored directly in this position.

Reference numeral 424 is information indicating the shooting date and time. FIG.
The information is read from the electronic timepiece 13 and recorded at this position. The shooting date and time is made up of year, month, day, hour, minute, and second information.

If appropriate information is input from the keyboard of FIG. 1, the information is recorded at this position. Note that the shooting location name 433 can be automatically derived using the above-described shooting location position information 428 if map information is stored in the video camera of this embodiment. In that case, the user does not need to input by hand (from the keyboard). Further, the weather information 434 can also be derived from the temperature information 430, the atmospheric pressure information 431, and the humidity information 432 by an appropriate algorithm, and in that case, it is not necessary to obtain it.

Such index data shown in FIG. 3 is triggered by the depression of the shutter switch 12.
It is recorded in the disk device 4 under the control of the central processing unit 2.

FIG. 4 shows a list of representative screens displayed on the display device 20 of the video camera. This makes it possible to understand at a glance what was shot with the camera. In addition, although not shown in FIG. 1, a suitable device for designating a position on the screen
By specifying an arbitrary representative screen and further instructing the projection of the video data, the moving image corresponding to the representative screen can be viewed on the screen, so that the confirmation of the video data becomes easy. As a device for designating the position on the screen, a mouse or a joystick often used in computers can be used, but for a camera, a switch for instructing movement in four directions is appropriate. Ah

Although only a list of representative screens is shown in FIG. 4, other related information, that is, photographing date and time, focal length,
Aperture value, screen movement information, etc. can be displayed correspondingly. Specifically, it is displayed so as to correspond to the related representative screen by being superimposed on the display of each representative screen or under each representative screen display. In addition, by selecting a desired representative screen with a position pointing device such as a mouse, it is possible to display corresponding related information.

The list display of the representative screens as shown in FIG. 4 can be output on paper by connecting a printer device to the outside of the camera. In the case of paper, the definition can be increased as compared with the electronic display screen, and since large paper can be used, more representative screens can be output than the screen display.

In this embodiment, the disk device (4 in FIG. 1) is used as the video recording medium, but it can be replaced with another video recording medium such as a magnetic tape device or a fixed memory device. In short, the technique of this embodiment can be applied as long as it can have an index part.

FIG. 5 is a PAD showing the control flow of the control program at the time of photographing executed by the central processing unit 2.
(Problem Analysis Diagram). This program is stored in the main memory 3 and is sequentially read and executed by the central processing unit 2.

As shown in step 501, this program is repeatedly executed while the camera switch (not shown) is ON.

First, step 501 is repeated until it is detected that the shutter switch 12 has been pressed when the shutter switch 12 is not being pressed, ie, when the shutter switch 12 is not being pressed. When it is detected that the shutter switch 12 has been pressed, the process proceeds to step 503.

At step 503, an area for recording new index data 42 is secured in the index area 41 of the disk device 4. Next, at step 504, the start address of the video data recording free area of the disk device 4 is stored in the video data address slot 421 and the representative screen slot 423 of the index data 42.
The start address of this free area for recording video data indicates that video data is to be recorded in this area. Note that the same address is also stored in the representative screen slot 423, but this indicates that the leading address is taken as the representative screen. Since the representative screen may be changed to another screen later, it is set as a slot independent of the video data address slot.

Next, at step 505, the date and time information is read from the electronic timepiece 13 and stored in the image pickup date and time slot 424 of the index data 42. Next, in step 506, the focal length information is read from the automatic focus adjustment mechanism 7 and stored in the focal length slot 425. Step 50
At 7, the aperture information is read from the automatic aperture adjustment mechanism 11 and stored in the aperture value slot 426. Step 508
Then, the zoom information is read from the zoom control mechanism 8 and stored in the screen movement information slot 427.

As described above, the video camera of this embodiment is placed on a fixed base such as a tripod, and a detector capable of detecting a mutual movement is provided between the video camera and the tripod and the output data thereof is electronically adjusted. When the video camera can read the information, the movement information such as pan (left and right) and tilt (up and down) is read from the detector and stored in the screen movement information slot 427 together with the zoom information.

Next, in step 509, the longitude and latitude values of the position where the camera exists from the GPS 14 are stored in the photographing location position information slot 428. Next, at step 510, the value of the angle indicating the direction, that is, the azimuth is read from the compass 15 and stored in the shooting direction information slot 429.

In addition, although not shown in FIG. 5 due to space, the outputs of the temperature measuring device 16, the atmospheric pressure measuring device 17 and the humidity measuring device 18 are also read, and the atmospheric temperature slot 430 and the atmospheric pressure slot 431 of the index data 42, Each of them is stored in the humidity slot 432.

Regarding the photographing place name slot 433, the weather slot 434, and the memorandum slot 435, if predetermined information is input in the main memory 3 in advance by the keyboard device 19, the necessary information is referred to by referring to the information. Stored in the slot.

Then, the process proceeds to step 511. Step 51
In No. 1, since it is known that the shutter switch 12 has already been pressed, the image data capturing process is repeated every 1/30 seconds while the switch 12 is being pressed. That is, in step 512, the picked-up image is read from the image pickup element 5, and the image data is stored in order from the beginning of the free area for recording image data of the disk device 4. Here, 1/30 second is the repetition frequency of the screen of the television signal.

The amount of video data is considerably large, and therefore the amount of processing is also large. Therefore, instead of the transfer processing by the central processing unit 2, the image pickup device 5 may directly output to the disk device 4.

When the shutter switch 12 is released, the loop of step 511 is exited. Then, in step 513, the data length of the captured video data is written in the video data length slot of the index data 42.

The above is repeated while the camera is switched on (step 501).

FIG. 6 shows a second embodiment of the present invention. Reference numeral 1 in FIG. 6 is a video camera similar to that in FIG. However, the communication interface device 22 is newly added. 23
Is a communication line. As the form of the communication line, a simple cable can be considered, but communication via the telephone network also falls within the scope of this embodiment.

Reference numeral 24 is a video recording and display device connected to the other end of the communication line. A communication interface device 25, a video display device 26, and a disk device 27 are built therein.

In the video camera 1, the results of shooting various scenes are stored in the disk device 4 in advance. At this time, similar to the first embodiment, as shown in FIG. 2, the representative screen of each scene is added as an index.

Under such a situation, it is now considered that the video data is transferred from the video camera 1 to the video recording / displaying device 24. For example, there is a case where a news cameraman of a television station shoots a news image on the spot and sends the result to the television station side.

From the standpoint of the television station side, one would first want to know what kind of video was taken as a whole. Therefore, first, the index data 42 in the index area 41 of the disk device 4 is referred to, and the representative screen data is sequentially sent to the video recording / displaying device 24 (on the television station side). In response to this, the video recording / displaying device 24 side displays a representative screen list on the screen of the video displaying device 26 in the same format as in FIG.

The user on the television station side sees this screen, selects one or more representative screens of the image he / she wants by using a position specifying device on the screen such as a mouse or a joystick, and the representative screen represents the representative screen. Instruct to send video data. Upon receiving this instruction, the disk camera 1 side refers to the index data 42 in the disk device 4 and sends the corresponding video data 40 to the video recording / displaying device 24 side. On the side of the video recording / display device 24, the sent video data is displayed on the display device 26 and the disk device 2
Store in 7.

According to the above method, the video recording / displaying device 2
On the side of 4, ie, the television station side, even if not all of the video data in the video camera is sent, by sending the representative screen list of the video data taken by the video camera first, it is possible to quickly know the outline of the taken video data. By sending only the necessary video data, it is not necessary to send extra video data, so that the transmission time of the entire video data can be shortened.

In this embodiment, the video sending device is a video camera, but the device is not limited to the video camera. It may be an appropriate video recording / reproducing device including the disk device 4 for storing the taken video data and the communication interface device 22. Furthermore, although the video recording medium on the sending side is a disk device, the present invention is not limited to this. It is also possible to consider a configuration in which only the index data is stored in the disk device and the video data is stored in the tape format medium. Further, a configuration in which the index data itself is stored in the same tape medium as the video data can be considered. Video recording and display device 24 on the receiving side
Also in the above, the video recording medium may be a tape type medium.

[0087]

As described above, according to the present invention, it is possible to record video data with an index in a video recording medium, particularly a video recording medium using a disk device or a fixed memory device. After that, the video data relating to the desired scene can be easily taken out directly. By using the representative screen data as an index and displaying or printing out the list of the representative screen data, desired scene video data can be easily searched. Moreover, since the related information such as the shooting date and time can be recorded together with the representative screen, the search can be further facilitated.

In the case of considering shooting an image with a video camera having such a function, and then editing or searching for it, work with only the image data recorded in time order on the magnetic tape as before. Compared with the case of doing so, it is not necessary to manually perform the fast-forwarding and rewinding operations of the magnetic tape, so that the work efficiency is improved. Further, when a disk device or a fixed memory device is used as the video recording medium, the time efficiency is greatly improved.

Considering the case of transferring photographed video data to another place, only the necessary video data needs to be transferred, so the transfer time is saved.
